Frozen evaporator coils in older homes
Why it happens here
North Main's historic homes often have undersized return ducts and leaky duct joints. That restricts airflow across the evaporator coil, which drops the coil temperature below freezing and causes ice buildup. It's worse in July when the system runs constantly.
Our approach
We thaw the coil, measure static pressure, and check airflow at each register. If the ductwork is the problem, we'll tell you and offer sealing or modification options. We fix the cause, not just the symptom.
